For example, if you have integrated an LLM API into a React or Next.js application, explain what the feature did and how users interacted with it.

Industry Context & Career Advice

Front-end engineering is increasingly connected to backend APIs, authentication, cloud deployment, real-time functionality, and AI-powered features. Modern front-end developers are often expected to understand more than HTML, CSS, and JavaScript.

This position is a good example of that broader role. Alongside React and Next.js, the engineer will work with REST and GraphQL APIs, Auth0, WebSockets, Vercel, Sentry, and AI-powered features.

For your resume, show that you can take a feature from design through production. A strong front-end portfolio should demonstrate responsive interfaces, reusable components, API integration, debugging, performance optimization, and real-world product development.

AI experience can also help differentiate candidates. You do not necessarily need to be an AI specialist, but experience integrating LLM APIs or using AI development tools can demonstrate that you are comfortable with the direction of modern software development.

What to Highlight on Your Resume

For this position, make these skills and experiences easy to find:

• 3+ years of front-end development
• Next.js
• React
• TypeScript
• JavaScript
• HTML5 and CSS3
• Production web applications
• REST APIs
• GraphQL
• Responsive design
• Reusable components
• Design systems

• OAuth
• WebSockets
• Socket.io
• GitHub
• Vercel
• Sentry
• Performance optimization
• Debugging and troubleshooting
• AI-powered applications
• LLM API integration
• Node.js or NestJS
• Cross-functional collaboration

When describing your experience, focus on what you built and the outcome. Instead of writing only “Developed React applications,” explain what application you built, what technologies you used, and what you improved.

A stronger resume bullet for this role could be:

Built and launched production-ready Next.js and React applications using TypeScript, integrating REST and GraphQL APIs while developing reusable, responsive components and optimizing front-end performance.

Customize this bullet with your actual projects, technologies, and measurable results.

Interview Preparation

Be prepared to discuss component structure, reusable components, state management, API integration, performance, code organization, and maintainability.

How do you turn a Figma design into a responsive web page?

Explain how you interpret the design, identify reusable components, handle different screen sizes, maintain accessibility, and work with designers when something needs clarification.

How would you integrate a REST or GraphQL API into a front-end application?

Think about data fetching, loading states, errors, authentication, caching, validation, and how the interface responds to API failures.

How would you improve the performance of a Next.js application?

Review topics such as rendering strategies, code splitting, image optimization, caching, bundle size, network requests, and identifying performance bottlenecks.

How would you implement real-time functionality with WebSockets?

Be ready to explain how the client establishes a connection, receives events, updates the UI, handles disconnections, and deals with potential errors.

How would you handle authentication with Auth0 or OAuth?

Review authentication flows, tokens, protected routes, session management, and the difference between authentication and authorization.

Tell us about a production application you built.

Choose a project where you can explain your responsibilities from development through deployment. Discuss the architecture, challenges, technologies, debugging process, and results.
